本文从虚化学势区域构造的正则扇形出发，研究了有限真实的化学势（$\mu_\mathrm{R}$）和低温下的核物质和夸克物质.基于大的$N_\mathrm{c}$估计，其中$N_\mathrm{c}$是颜色的数量，我们可以从典型扇区讨论有限$\mu_\mathrm{R}$处的限制-去限制性质。我们发现在$\mu_\martrm {R} \sim M_\martrm {B}/N_\martrm {c}$处的正则扇区的急剧变化，其中$M_\martrm {B}$是最低的重子质量，是发生在大N_\martrm {c}$区域，并且与夸克图像相匹配.此外，我们还从典型扇区的结构讨论了色超导电性和手征性质。即使在目前的解剖从典型的部门，我们可以有合适的图片为密集的QCD物质。
We investigate the nuclear and the quark matter at finite real chemical potential ($\mu_\mathrm{R}$) and low temperature from the viewpoint of the canonical sectors constructed via the imaginary chemical potential region. Based on the large $N_\mathrm{c}$ estimation, where $N_\mathrm{c}$ is the number of color, we can discuss the confinement-deconfinement nature at finite $\mu_\mathrm{R}$ from the canonical sectors. We found the expectation that the sharp change of canonical sectors at $\mu_\mathrm{R} \sim M_\mathrm{B}/N_\mathrm{c}$, where $M_\mathrm{B}$ is the lowest baryon mass, is happen in the large $N_\mathrm{c}$ regime, and it is matched with the quarkyonic picture. In addition, we discussed the color superconductivity and the chiral properties from the structure of canonical sectors. Even in the present anatomy from the canonical sectors, we can have the suitable picture for the dense QCD matter.
